I usually avoid proprietary cloud services because of freedom, privacy and vendor lock-in concerns. In addition, there are some excellent libre (and hosted) services such as WordPress , Wikipedia and OpenShift which don’t have the above problems. Thirdly, there are every day Free Software tools such as Fedora GNU/Linux , Libreoffice , and git-annex-assistant which make my computing much more powerful. Finally, there are some..

I met Alaa Abd El Fattah in May 2013 in Cairo. This was about two years after the initial revolution occurred that removed Hosni Mubarak from power, and nearly a year into the presidency of Mohamed Morsi from the Muslim Brotherhood. At the time Alaa was out on bail, facing charges for his involvement in demonstrations several months earlier (he was organizing against provisions in the new constitution that allowed civilians to be tried in ..

File Hashing: If you look close enough, even files have fingerprints

A little while back I spent some time looking at an interesting issue with a colleage. He was trying to load a virtual machine from an .OVA but kept recieving error messages as he loaded it that the file was invalid. Somehow though, other people used the same file. This one could be fun to diagnose. To start with, the premise of our argument has a problem: it wasn't the same file but rather a copy of the file.

The Mona Lisa Leonardo da Vinci’s Mona Lisa is one of the most famous paintings of all time. And there has always been a discussion around her enigmatic smile. He used a trademark Renaissance technique called sfumato, which involves many thin layers of glaze mixed with subtle pigments. The striking result is that when you look directly at Mona Lisa’s smile, it seems to disappear. But when you look at the background your peripherals see a sm..

Preface I have been asked many times what closures are and how they work. There are many resources available to learn this concept, but they are not always clear to everyone. This has led me to put together my own approach to exchanging the information. I will supply code samples. //> denotes an output or return. Before discussing closures, it is important to review how functions work in JavaScript. Introduction to functions If a function d..

At first I attributed my absence of enthusiasm in a medium that I previously enjoyed so immensely a by-product of the increased demands on my time as of late. However, upon further consideration, and after yet another week of but one entry here in a list that previously contained double-digit items, I realized the true reason behind this unfortunate change: my interests had shifted. Just as I no longer derive the same pleasure in reading ab..

Back to the brain we go. I already had snails eating food in jars before, but it was kind of a hack. Each snail would just eat a bite of whatever consumable item was in the jar. When I stupidly decided to try to make a simple snail brain, I knew I’d have to make things like eating fit into it. Today I made a very rough version of something like that.

It’s occasionally useful when writing map/reduce jobs to get a hold of the current filename that’s being processed. There’s a few ways to do this, depending on the version of Spark that you’re using. Spark 1.1.0 introduced a new method on HadoopRDD that makes this super easy: import org.apache.hadoop.io.LongWritable import org.apache.hadoop.io.Text import org.apache.hadoop.mapred. { FileSplit , TextInputFormat } imp....

Yesterday I gave a talk at Dev Workshop Conf introducing the basic concepts of vertex and fragment shaders. Unfortunately I don't have a video, just this one potato picture: It's probably for the best, because Chrome locked up on me halfway through. The slide deck is pretty cool though. It includes over 20 interactive WebGL samples, complete with source code. Check it out and let me know what you think!

A bi-temporal data model is a fancy way of saying that all tables have 2 pairs of dates: business from/to, and audit from/to. The business dates track expected day-over-day changes in business data such as the varying quantities of widgets in stock. The audit dates are used to track when the data was loaded into the database, and any data fixes applied by IT. In essence, every table contains the current record as well as the full log of..

Shortly after introducing Mirah support for Codename One , Steve is back with something that is arguably even more impressive. Over the weekend Steve released a tool called CN1ML which is an HTML subset markup language that allows you to effectively build Codename One UI’s with HTML. This isn’t another embedded webbrowser or HTMLComponent, this is a tool that statically translates HTML syntax into Codename One compon..

Over the past few days I’ve paused work on the brain to tackle snail movement on the client. I ended up using Latchet , a Laravel-specific extended version of Ratchet. To start with I just wanted to get something running. I think I ended up doing this in a really roundabout way…basically we subscribe to a specific jar topic on the client, then ping the server every 5 seconds to get back the target position of each snail within that jar..

Incredible to think that today, in our modern society, things like this still happen. Not only do these sorts of things happen though, but they fly under the radar as well. Harrowing, to say the least. Permalink.

AirControl is a tool to control AirPlay Mirroring from the command line. TL;DR: it’s open source and available in our GitHub repo . If you’re interested in the details of how we got it working, read on. Once a month, the Engineering team has a Hack Day. Anybody can work on anything they like, be it discovering a new programming language, speeding up our test suite, or, in the case at hand, building a terminal tool to control AirPlay....

I happened across Expedition Portal the other day after the same tangent led me to Triple Aught Design . Already more than an hour down this rabbit hole of outdoor expeditions and the gear enthusiasts use on such trips, I started clicking — and clicking, and then I clicked some more until I had filled my entire Safari tab bar. And then, I began reading this humorous article by Mathew Scott from March of last year: Death by Idiotic Purch..

Our email infrastructure is flawed. We need to reconsider our approach to email to make it safer - and easier. Most people think of email like sending a letter in the post, a person-to-person communication in a sealed envelope. However, email is more like sending a postcard. Multiple actors have access to the contents and we need to be careful who we ask to convey our communication.

During September of last year I saw this incredible story pass by, but I let it go without comment. This time, however, I refused to make the same mistake. It’s so easy for us to sit in our homes decrying America’s defense budget, and say things like, “I look forward to the day the Air Force has a bake sale in order to raise money.” America’s military is not some faceless organization used to enforce the will of politicians, though: these..

In the first six parts of our series, we examined some of the power that Fiddler has to offer us: we covered remote debugging, composing requests, breakpoints, autoresponders, plugins, and a bit of FiddlerScript. So what's next? There's still an incredible amount that Fiddler can do, but despite the “Land Before Time”-esque post names, this was never meant to be a comprehensive Fiddler feature tutorial. The series was just meant to cover so..

One of our pro users alerted us to an issue with iOS 8 that might trigger a case where apps can’t be installed OTA (Over the air, via QR or email links) and only installed via itunes. We didn’t experience this issue ourselves but it seems to be affecting many developers (not Codename One specific). This is due to caching of package bundle ID’s and he provided some resources here that might be of interest:

Well friends, Lemma is still on pause while I do some contract work. I also have only a few slides done for my shader presentation next week. This whole month is crazy. But I thought I'd hijack this dev blog to show you the game I'm working on, because it's starting to look kinda cool! It's a top-down iOS survival shooter designed as a sort of franchise tie-in. The budget is pretty low so most of the assets are pulled from the Unity asset..
